FRUIT-JUICE IEXTRACTOR.

Application led August 10, 1925. Serial No. 49,329.

This invention relates to improvements in fruit juice ext-ractors, moreparticularly to devices for extracting the juice from oranges, lemons,grape fruit, and the like, and has for one ot its objects to provide asimply constructed apparatus whereby an extract-or .element may becaused to rotate when pressure is applied thereto, or to the section offruit disposed thereon, to thoroughly extract the juices therefrom andpermit them to fall into a suitable receptacle.

Another object of the invention is to provide a device of this characterhaving means whereby the extracted juices are thrown by centrifugalforce away from the extractor element vand thereby prevented 'fromlodgement thereon.

Another object of the invention is to pro` vide a device of thischaracter wherein the several parts are separable for cleansing or forthe renewal of broken or impaired parts without discarding the unbrokenor unimpaired portions.

In the drawings illustrative of the preferred embodiment of theinvention. l Fig. l is a longitudinal sectional elevation of theimproved device.

Fig. 2 is a top plan view. v

The improved device includes a body preferably cylindrical and formedwith vertical sides 10 and with the bottom l1 sloping and disposedintermediate the sides, thereby forming a chamber orspace 12 benea'ththe sloping bottom.

The lower edge of the body is preferably supplied with supporting Vfeet13 and its uper edge inturned in the form of anoverlianging flange 14surrounding the upper open endmf said body. l

The space'within the body above the floor constitutes the receptacle inwhich the extracted juices are rst received, and .which escape through alateral opening 15 and over a sloping spout 16 at the lower end of thebottom 11.

Formed upon the sloping bottom 11 is a perforated hub or boss 17, theperforation being internally threaded with a double or quick actionthread, the hub operating as aguard to prevent the extracted juices fromrunning through the threaded opening into the chamber 12, as willbeobvious.

Operating through the threaded opening in the hub 17 is a member 18having double or quick action threads to correspond and By thisDepending from the bottom of the iioor l 11 are guide rods 28 andslidable on the guide rods is a cross head member 24, the latter beingyieldab y supported on the rods, by springs 25.

At its lower end the threaded member 18 is reduced as shown at 26 androtatively stepped by the reduced portion in a socket in the cross head24, the socket having a ball race 27 to receive anti friction balls 28.

At its lower end the reduced portion 26 of the member 18 is formed withan encircling channel'29 to receive a, spring key member 30, to enablethe member 18 to ybe detachably and rotatively locked to the cross head.

The springs25 are supported by adjusting nuts 31, to enable the tensionof the springs to be controlled.

By this simple arrangement, when a section of fruit, for instance thehalf of a lemon, orange, grape fruit or the like is placed upon theextractor and `iorced downwardly and held from turning by the hand, thequick action threads of the member 18 coacting withthe quick actionthreads of the hub 17 will cause the member 18 and the extractor carriedthereby to be rotated as theymove downwardly and thus effectuallyextract the juices and cause them to flow into the trough 21 from whichthey will escape through the f orifices l22 and be also thrownA by thecentrifugal force generated by the rotating extractor a'nd its troughagainst the side walls of the receptacle chamber and flow' thence.through the opening l15 and spout 16 into a suitable vessel, not shown,venting the wardly.

In the meantime the downward movement of the member 18 will depress thecross headA 24 against the resist-ance of the springs 25, and when the.downward pressure is removed the reaction of the springs will returnthe the flange 14 prejuices from lbeing thrown up-` member 18 andextractor to its former position when the extracted fruit section can bedetached.

The body 10 will be formed of glass, glazed porcelain, aluminum or othernoncorrosive material, while the extractor element will likewise beformed of glass, porcelain, aluminum or other noncorrosive material orcompounds. 'lhe metal parts will also be of' noncorrosive compounds orplated, or other wise protected from the action of the fruit juices. v

As before stated all the parts are separable for cleansing and readilydisconnected and assembled.

Claims:
